Many hold strong beliefs and opinions, however not many know the roots of their belief. If a person agrees to explore it, both of you will learn something new and fascinating. The problem is finding someone who wants to think and ask the questions. This goes for both. Many want to “convince” someone, but how much do you truly know about the thing you’re trying to prove?
This also comes back to the “why?” game so many kids play. Parents get annoyed by it, but are they really annoyed at the game or their lack of knowledge depth? Play the game, find out how deep you lake of knowledge goes
I remember asking my father in law why he doesn’t believe in climate change. It boiled down to him saying the democrats just want to control us. When I asked why he said just so they have more power for power’s sake. I told him I’m willing to accept that politicians can be like that (because many are) but why does he believe that the republicans are immune to this craving of power or if he thought republicans denying climate change could be just for the sake of controlling people to get more power (like he accused democrats of) and surprise surprise he couldn’t give me an answer other than democrats are corrupt and want more power but republicans don’t (which isn’t an answer because I’m asking why).
